-9+8k=7+4k(if there is no solution,type in ''no solution'') k= Answer
Shtirlitz [24]

Answer:

k = 4

Step-by-step explanation:

-9 +8k = 7+4k

Subtract 4k from each side

-9 + 4k = 7

Add 9 to each side

4k = 16

Divide by 4

k = 4

Plug in the value you got for k:

-9 + 8(4)  ?  7 + 4(4)

-9 + 32  ?  7 + 16

23  ? 23

23 = 23

Find the lateral area for the pyramid with the equilateral base
likoan [24]
<h3>The lateral area for the pyramid with the equilateral base is 144 square units</h3>

<em><u>Solution:</u></em>

The given pyramid has 3 lateral triangular side

The figure is attached below

Base of triangle = 12 unit

<em><u>Find the perpendicular</u></em>

By Pythagoras theorem

hypotenuse^2 = opposite^2 + adjacent^2

Therefore,

opposite^2 = 10^2 - 6^2\\\\opposite^2 = 100 - 36\\\\opposite^2 = 64\\\\opposite = 8

<em><u>Find the lateral surface area of 1 triangle</u></em>

\text{ Area of 1 lateral triangle } = \frac{1}{2} \times opposite \times base

\text{ Area of 1 lateral triangle } = \frac{1}{2} \times 8 \times 12\\\\\text{ Area of 1 lateral triangle } = 48

<em><u>Thus, lateral surface area of 3 triangle is:</u></em>

3 x 48 = 144

Thus lateral area for the pyramid with the equilateral base is 144 square units
